Video Capture and display out of sync

We are working on video application on BF609, we are able to run the video capture (composite ) and display HDMI, but the problem if we add any processing on the core with video cpature and display ---> we observe video out of syn in both side (capture and display).

It appears to be an issue related to system bandwidth, causing may be because your code is not optimised properly. So, it would be best if you can contact private support channel, then we can take a closer look at your application, how it is implemented and best ways to optimise it.
